Worms or chickens?

What you see here is our four chickens scratching around in the compost pile for worms. I spent an entire day chipping yard waste, and the result was this modest pile of mulch, maybe four feet tall. I was amazed at how quickly the red wigglers colonized the pile. It's just thick with them now, and when we let the chickens out to forage, they rush to the compost heap as if it's happy hour and they're running to the bar. I do feel sorry for the little worms, but this is the food chain, after all. The hens leave their droppings, which in turn will become food for future generations of worms. (You can meet the chickens here.)
